Add table support to the schema differ, limited to whole-table create and drop: - introspect user tables (relkind='r', excluding system schemas) and their columns, ordered by attnum, with types from format_type - CREATE TABLE when present in target only - DROP TABLE when present in source only - no-op when a table exists identically on both sides Column-level diffing (adds/drops/type changes), constraints, indexes and defaults are intentionally out of scope for this increment.

Rename the full-database model from Schema to DbInfo and introduce a real Schema type for Postgres namespaces (name + table_by_name keyed by table name), resolving the 'schema' overload. Extensions stay at the DbInfo level since they are unique per database by name; nesting them under a schema would misrepresent SET SCHEMA as drop+create. Add schema create/drop diffing: - introspect user namespaces from pg_namespace (excluding pg_*, information_schema and extension-owned schemas) - CREATE SCHEMA / DROP SCHEMA, ordered so schemas are created before their contents and dropped after them (creates -> extensions -> tables -> drops) build_schema -> build_db_info, generate_schema_migration_sql -> generate_migration_sql.
